ject being, first, to provide such an anchor which has great holding power; second, to provide improved means for boring the anchor into the ground and for securing and holding blades thereof in solid earth after the anchor has been bored in sufficiently, and, third, to provide improved holding blades or means for securing the anchor in place.

The anchors generally in use which have holding blades or prongs adapted to catch in the solid earth require a hole to be bored, so that they can be inserted bodily therein, and then the blades or prongs spread out into the solid earth by a mechanical means or by pulling the anchor out of the hole slightly. Then, again, there are other anchors in use which may be bored into the earth; but these anchors have no means to be spread out to catch in the solid earth. In this latter form of anchor the earth which has been loosened by boring the anchor into it is depended upon to hold the anchor in place.

In my present invention I provide an anchor which has the combined advantages of both of the above-mentioned types, as it does not require any hole to be made in the earth therefor, and at the same time does not depend solely upon the loosened earth to hold it in place. In this anchor I provide an augerlike end portion, which is bored into the earth by turning it in one direction, and disk-like blades or portions near the said auger-like end, which are then forced outward into'the undisturbed earth after the auger has been fully bored down by turning the boring handle or wrench in the opposite direction. It will be readily seen that this anchor has a double holding power due to the loosened earth above the auger portion and the extension-blades holding in the solid earth. I preferably rovide a wrench a art from the anchor for oring same into t e earth and for opening the extension-blades. After the anchor is bored into the earth as far as is desired and the blades opened the wrench may be removed. If one or both of the blades should strike an obstruction while being spread out, the wrench may be turned in the opposite direction and the blades closed up and the anchor bored down deeper, so that the said obstruction will not'interfere with the blades when they are again opened.

I will now more particularly describe my invention by reference. to the drawings, in which Figure 1 is a side elevation of the anchor with the extension-blades shown closed and the wrench shown in cross-section. Fig. 2 is afplan view of Fig. 1 with a portion of the top 0 Fig. 1 removed, showing the extensionblades extended in dotted lines. Fig. 3 is a side elevation of a portion of the lower end of the anchor and wrench, taken-at right angles to Fig. 1. Fig. 4- is a view showin how the anchor is applied in guying a telephone-pole or the like, and Figs..5 and 6 are detailed.

views of the respectlve extension-blades. Like characters refer to like parts in the several figures.

The disk'a, preferably made of iron or steel, is cut away, as at b, and is provided with an offset portion 0, which is comparatively sharp and is used as an auger-blade to screw the disk 0. into the earth when turned in a forward direction. A point (1 is provided un= derneath the disk ato guide same in boring. The disk a and point or spur-d are rigidly attached to the rod or stem e, which is provided with an eye f at its upper end, in which a rope, cable, wire, or the like may be attached. The portibns a, d, and e may all be one and the same piece or may be made of separatepieces and secured together.

Two extension-blades g and h are placed upon the disk a, as shown in Fig. 1. Blade g is cut away between I) and i, Fig. 2, tea litwit gear-teeth i, is provided with a small projecting pin is, and 1s ivoted to disk a. at Z y a screw or rivet, so t at it may be swung out to the position 9 Blade h is cut away between 12 and mto alittle past the center of the auger, is rovided with ear-teeth m, is provided wit a projecting ob n, is cut away at 0, is cut awayat s, and is pivotedat tle past the center of the auger, is provided,

m of blades g and h, and is held in p by a screw or rivet, so that it may be swung out to the position it. The disk a is pro vided with projectingportions g and 7 near the edge thereof to form bearings for blade g. The cut-away portionso and s of blade 71. fit around the portions 9 and 1, respectively, when blade h is in the (position shown in Fig. 1. A plate t, provide with a transverse rib u on top thereof and a pinion-gear v on the bottom thereof, is placed upon the rod 6, so that the gear v meshes with the gears iband 7 place pin w, which passes through ro e. The

plate tis cut away at a: to engage in k, which acts as a stop for the plate t w en same is turned in the direction to bore the anchor into the earth.

The wrench y is enough to pass over t e enlarged en 6 an iscut awa over the rib u, as s own in Fi s. 1 and 3. The handle portions 2 z are preerably screwed into a collar at the upper end of pi e y and are detachable for convenience. T e clamp 1 is clamped to the rod 6 against the upper end of the wrench to hold the latter down on referably a at; lfargg In using the anchor the Wrench 3 is first slip ed over the rod e, as shown in Figs. 1

an 3, and the clamp 'y put in place, the blades 9 and 7 being closed in, as shown in these figures. Then the spur d is stuck into the earth where it is desired to sink the anchor, and the wrench is turned in one direction, so as to bore the anchor into the earth, the plate t engaging the pin 7c and the teeth of inion v engaging portions of the blades g and it, so as to cause the turning of the wrench to turn the anchor as a whole. When the anchor has been bored into the earth as far as desired ,the wrench is turned in the opposits direction, the disk a, and stem 6 remaining stationary and the pinion v turning backward and gearing with the teeth i and m of blades 9 and h, and thereb' spreading the latter out into the undistur ed earth in the ositions shown in dottedlines at g and h 0 Fig. 2. When the blades 9 and h are thrown out as 'far as they will go, the clamp y? and wrenchy may be removed, leaving the anchor in the earth, as shown in Fig. hen the guy-strand 2 may be fastened to the pole and anchor and tightened as desired.

The plate 15 me. be nearly as large in diameter as the bla es g and h, so as to bear on the latter over considerable surface thereof and more firmly hold same from buckling or turning up, due to an excessive strain there- I wish it to be understood that I do not desire to limit this invention to the exact details of construction as herein shown, as many sli ht modifications therein may be made wit out departing from the scope of the invention.
